7035L20PF

Memory IC Overview

The 7035L20PF is an asynchronous dual-port static RAM with a density of 144 Kbit, organized as 8K words by 18 bits. It operates on a single 5V power supply and features a 20 ns access time. The device is housed in a 100-pin TQFP package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent reads and writes from either port without external arbitration logic.
• Integrated hardware semaphore signaling and interrupt flags facilitate efficient data synchronization between ports.
• Supports battery backup operation for data retention at low voltages while maintaining TTL-compatible interface levels.

Memory IC Applications

• Stand-alone high-speed memory systems requiring concurrent access
• Master/Slave configurations for wider word-length data processing
• Industrial control systems operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm voltage grade and temperature range. Confirm RoHS compliance status and lead-free availability for current production units. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 5V asynchronous dual-port SRAM with 18-bit width is required. Ensure the design accommodates the 100-pin TQFP footprint. Verify that the system timing requirements align with the 20 ns access speed and that power supply constraints match the specified voltage range.

Memory IC Part Context

This part belongs to the Renesas 7035 series of dual-port RAMs. It serves as a core memory solution for applications needing high-bandwidth data exchange between two processors or controllers without complex external logic overhead.

Memory IC Replacement Considerations

The IDT7035L20PF is a documented equivalent part number. Verify pinout compatibility and electrical specifications before substitution.
